RICHARD GIBBON, OF MOBEETIE, TEXAS.

SASH-FASTENER.

faPECIFICATIQN forming part of Letters Patent No. 338,837, dated March30, 1886.

Application filed September 18, 1885. Serial No. 177,451. (No model.)

To all whom it may concern:

Be it known that I, RICHARD GIBBON, of M obeetie, in the county ofWheeler and State of Texas, have invented a new and ImprovedSash-Fastening, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improved device forholding a sash at any desired elevation, which device is strong anddurable and simple in construction and can be applied on any window.

The invention consists in the construction of parts and details andcombinations of the same, as will be fully described and set forthhereinafter, and pointed outin the claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure, l is a sectional plan view of my improved sash-fastening. Fig. 2is a longitudinal sectional view of the fastening. Fig. 3is a face viewof the escutcheon. Fig. 4 is a side view of one of the side plates ofthe casing.

The casing A is provided with an end plate, B, and with two side platesor pieces, (3, each having an upwardly-projecting lug, D, having acentral opening, E, through which a squared spindle, F, can be passedfreely, the said spindle projecting from the front side of thewindowcasing G, and being provided with a knob, H. The spindle F is alsopassed through an escutcheon, J, fastened on the front of thewindow-casing G, and having a serrated or cogged opening, K, in itscenter, into which a serrated or cogged part, L, of the spindle F at theknob H can be passed. A cross-pin, M, in the spindle F, behind theescutcheon J, prevents pulling the spindle F out too far. The end plateof the casing A is provided with an opening,through which a slidingbolt, N, in the casing A can pass, on the upper edge of which bolt arack, O, is formed, with which rack a pinion, P, engages, the saidpinion having collars P on the sides, which collars are passed into theaperture in the lug D to turn in the same. The sliding bolt N has ahead, Q, on its outer end. The plate B is countersunk in thepulley-slide R, and the casingA projectsinto the v window-casing.

The operation is as follows: To hold the sash S at any desiredelevation, the-spindle F is pulled out until the serrated or cogged partL is withdrawn entirely from the escutcheon, and then the spindle F isturned on its longitudinal axis in such a manner as to cause the pinionP to revolve in such a manner as to move and press the bolt-head Q,firmly against the edge of the sash S. Then the spindle F is pushedinward, and the part L is passed into the opening K in the escutcheon J,thus preventing the spindle F from revolving, whereby the bolt N islocked in place, and thus the sash is locked in place. To release thesash the spindle F is withdrawn until the part L can clear the aperturein the escutchcon, and then the spindle is turned in such a manner as towithdraw the head Q from the sash S,which can then be moved up and downfreely.

One ortwo of the above-described devices can be applied to each sash.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent- The combination of the casing A, havingapertured ears I), and a front plate, B, of the rack-bolt N, having ahead, Q, beveled on its rear face to fit a corresponding beveled openingin the front plate, the pinion P, and the spindle F, the beveled headbeing adapted to enter the beveled opening of the front plate and lieflush with the outer surface of said front plate.

RICHARD GIBBON.
